Maybe that's when bad scripts are written, when you choose the theme first. I consider that I've something to say when I've thought of a person, a moment, a single beat of the heart, that I think is true and interesting, and therefore should be seen.

I would rather be confused for 10 minutes than bored for 5 seconds.

The Doctor: Rose... before I go, I just want to tell you: you were fantastic. Absolutely fantastic. And do you know what? [Pause] So was I!

Daleks: [simultaneously] Exterminate! Exterminate! [They fire their weapons, none of which so much as touch the Doctor] The Doctor: Is that it? Useless! Nul points! [to Rose and Jack] It's all right, you can come out; that forcefield can hold back anything! Jack Harkness: Almost anything. [pause] The Doctor: Yes, but I wasn't going to tell them that. Thanks.

Buffy the Vampire Slayer showed the whole world, and an entire sprawling industry, that writing monsters and demons and end-of-the-world is not hack-work, it can challenge the best. Joss Whedon raised the bar for every writer - not just genre or niche writers, but every single one of us.

I love having debates with people when they are debates but some people, you just can't. Some people shouldn't be given the oxygen.

In the end I sort of though we created a companion who was so alive and dynamic and so wedded to the doctor that you’d need a whole universe to contain her in. The only way to get rid of her is to send her into a parallel world from which she can never return; otherwise she would stay with the doctor forever.
